Disregard the last post. I found out how to do it in Outlook's help.
It was under "Country Code"
____________________________________________________________________________
_
Add the country code to numbers you enter
1.. In Contacts, on the Actions menu, point to Call Contact, and
then click New Call.
2.. Click Dialing Options.
3.. Select the Automatically add country code to local phone numbers
check box.
The country/region code added is for the selection in the
Country/region list on the General tab of the Edit Location dialog box (in
the New Call dialog box, click Dialing Properties, and then click Edit).
Note If the Automatically add country code to local phone numbers
check box is not available, Microsoft Outlook doesn't recognize the phone
number format for the specified country code and cannot automatically format
phone numbers.
